    Abstract: A channel identification system and method are provided to automatically identify ports of a base station (e.g., an eNodeB) to route downlink signals to appropriate access points in a telecommunication system. Primary and secondary synchronization signals may be identified in the downlink signals transmitted by the base station. A broadcast channel may be decoded for a downlink signal including the primary and secondary synchronization signals. Signal information may be used to extract a first cell-specific reference signal and generate a second cell-specific reference signal corresponding to one or more ports of the base station. The first and second cell-specific reference signals may be correlated to verify the identity of the channel corresponding to the ports of the base station.

    Abstract: A cable spool includes first and second curved flanges extending radially outwardly from first and second axial ends of a drum. The flanges have outer edges that cooperate to define an annular slot providing access to a passageway surrounding the drum. The slot has a width that is less than half the height of the drum. A cable is wrapped around the drum. A closure having an environmentally sealed interior may receive an end of the cable. A second cable can be deployed from a second spool and coupled to the end of the cable within the closure. The second spool can be mounted with the cable spool. A cover can be placed over the spools for aesthetic or protection reasons.

    Abstract: Embodiments described herein provide for a distributed antenna system including a host unit and an active antenna unit (AAU). The AAU is configured to wirelessly communicate with, and to receive uplink radio frequency (RF) signals from, one or more wireless devices. The AAU is further configured to sample the uplink RF signals to generate digitized RF data. The AAU includes an Ethernet interface for receiving Internet Protocol (IP) formatted data from an IP device coupled to the Ethernet interface. The AAU is configured to transport the digitized RF data and the IP formatted data over a transport signal to the host unit, the transport signal including a plurality of bits. The AAU is configured to adaptively adjust the number of bits that are allocated to the digitized RF data and the number of bits that are allocated to the IP formatted data.
